Mutations in the canine parvovirus capsid make it more infectious
Canine parvovirus (CPV) is closely related to the feline panleukopenia virus (FPV), also a parvovirus, that infects domestic cats and some non-domestic carnivores.
Users show off innovative work at BioSAXS Essentials V workshop
The Macromolecular Diffraction Facility at the Cornell High Energy Synchrotron Source (MacCHESS) held its fifth annual BioSAXS Essentials workshop on October 30 to November 1, 2014.
Fine details of transcribing DNA to RNA
RNA polymerase (RNAP) assembles an RNA strand corresponding to the DNA sequence of a gene, in a precisely choreographed series of molecular motions.
Professor Eddy Arnold elected as 2014 American Crystallographic Association Fellow
Eddy Arnold, Board of Governors Professor of Chemistry and Chemical Biology at Rutgers University, and Resident Faculty Member at the Center for Advanced Biotechnology and Medicine (CABM), was recently elected as a Fellow of the American Crystallographic Association (ACA).
CRISPR Cas3 structure
Within the past decade it was discovered that many cells have an adaptive immune system to fight off foreign RNA or DNA which may have been inserted by a viral, plasmid or transposon attack.
Unwrapping DNA from nucleosomes
DNA in the cell must be stored in a compact form (or it wouldn't fit) that also allows it to be translated to RNA, and to be copied when a cell divides.
Electrostatic interactions help an enzyme do its job
A catalytic enzyme facilitates a reaction by bringing one or more molecules into its active site and there providing an environment conducive to the reaction.
Proteins at work inside a membrane
Proteases, enzymes that cleave proteins, are found both free-floating and embedded in membranes. Reactions involving the former are well understood, but the workings of the latter have remained mysterious – how are reactions controlled inside the viscous, two-dimensional membrane, from which water is excluded?
